+ 1 on Cullen Cable. The only downside is their product rarely shows up on the used market and there is probably a 3+ week wait if you order something directly from them. I have no experience with Pangea products; but, a friend of mine who works in the audio business was impressed with them based on their price points (most will tell you the same about Cullen Cable).
Based on your budget and browsing the current Audiogon listings, there appear to be intriguing options from: Silnote, Audience, Morrow Audio, Audio Art, Nordost, Synergistic Labs & Acoustic Zen.
Good luck in your search!
